Sparked by bands such as the Rolling Stones, Yardbirds and Cream, fans and musicians were fascinated by authentic Chicago blues artists such as Muddy Waters.

Gallagher had an extensive knowledge of this kind of music, although he tended to play down arguments about what was "pure" blues.

The song "I Could've Had Religion" was Gallagher's salute to what he called the "redemption style blues" of the Robert Wilkins and Gary Davis.

[citation needed] The finale is the straight-ahead hard rocking "Bullfrog Blues" written by William Harris.

Gallagher switches back to the electric guitar and the full band and gives bassist Gerry McAvoy and drummer Wilgar Campbell, a chance to solo.

[citation needed] With the CD release, two additional blues songs were added: "What in the World" and "Hoodoo Man".
